3 9/16" Long Drill Bits | McMaster-Carr

Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.

Short Length—The most rigid bits for drilling the straightest holes.

Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.

Chip-Clearing Carbide Drill Bits


Jobbers' Length Parabolic Flute Round Shank	Standard

The hardest and most wear-resistant bits, the flutes clear chips and improve coolant flow. They prevent clogs and dissipate heat that can damage the bit and the hole. Carbide bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.

Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.

Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.

Uncoated—Excellent for a range of materials but won't last as long as coated bits.

High-Speed Steel Ball End Mills for Aluminum, Brass, and Bronze


Ball Cut Style

With a higher helix angle than standard high-speed steel end mills, these clear more chips and generate less heat, making them good for milling soft material, such as aluminum, brass and bronze. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

High-Speed Steel Square End Mills for Aluminum, Brass, and Bronze

2 Flutes

3 Flutes

With a higher helix angle than standard high-speed steel end mills, these clear more chips and generate less heat, making them good for milling soft material, such as aluminum, brass and bronze. They are center cutting for making plunge cuts into surfaces and have a square-end cut style for milling square slots, pockets, and edges.

Uncoated High-Speed Steel—Use uncoated end mills for general purpose milling and short production runs.

Titanium Carbon Nitride (TiCN)-Coated High-Speed Steel—Use titanium carbon nitride (TiCN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum.

2 Flutes—End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.

3 Flutes—End mills with three flutes produce a finer finish and operate with less vibration when run at high speeds.

Impact Wrench Pipe and Conduit Taps

Cut threads inside pipe and conduit 15 times faster than by hand. Made with an oversized shank and hardened high-speed steel, these taps are built to handle the high torque of impact wrenches to cut material quickly. Your wrench’s rapid hammering keeps these taps moving forward for smooth, continuous cutting. Those rapid blows also help break and clear chips as you cut, so you don’t need to pause and reverse, even in large holes and tough materials. This also means the tap is less likely to jam on chips and snap.

You’ll need a VersaDrive chuck (sold separately) to install these taps into your impact wrench. You can also get chucks for impact drivers (sold separately).

NPT Thread About NPT Thread

Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.

Taper Chamfer—Good for both starting holes and threading through holes. These taps have the longest taper to gradually engage with the material, reducing the force needed to turn them. They can't reach the bottom of blind holes, however, so you will likely need to finish with a bottoming-chamfer tap.

Accessories for Taps

Required Chucks

Quick-Change

Strong-Hold

These chucks mount directly onto the square drive of your impact wrench. They work with any tool with a VersaDrive hex shank, so you don’t need to swap chucks to use drill bits, reamers, and other tools.

Quick-Change Pull-Back Tool Release—Require just one hand to load. Push your tool in the chuck until you hear the ball detents click into place. To remove your tool, pull back the collar.

Strong-Hold Push-Forward Tool Release—Hold cutting tools more securely than quick-change chucks. To insert and remove cutting tools, you must push a collar forward. Since impact force drives your cutting tool the opposite way, it can’t come loose from the chuck while you work.

Manganese Phosphate-Coated Steel—The coating on these chucks prevents rust.

With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. They have a square end for milling square slots, pockets, and edges.

End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.

Uncoated Cobalt Steel—Use uncoated end mills for general purpose milling and short production runs.
